Our little girl’s active vocabulary still tends to be mainly French, but when she has a word in one language, she usually sticks with it.
The other day, Daddy asked her for the French version of one of her first words in German, namely cheese (Käse/fromage):
Daddy: “Tu sais dire fromage?” (Can you say “cheese”?)
She, cheese in hand, a huge smile on her face: “Oui! Kä!”
